STRING-TYPE MUSICAL INSTRUMENT.

Application filed February 14,

My invention relates to improvements in musical instruments of thestring type, as pianos, harps, etc. The objects of my invention are: p

First: To produce musical instruments of the stringtype, whoseindividual group of tone producing strings can be adjusted, regulated,and set for any desired tone pitch, by specially provided adjusting andregulating means. 1

Second: To provide means by which all of the tone producing strings canbe adjusted to any higher or lower tone pitch, at one and the same time.

Third: To produce a simplified construction of a string supportingframe, whose individual members are so designed as to be easilyassembled and disassembled, thus materially reducing the cost ofproduction,

Fourth: To arrange and design the complete string supporting frameequipment in such manner as to constitute a self contained unitpermitting an easy and quick removal or interchange with another similarunit whenever desired.

A typical embodiment of my invention is represented in the accompanyingdrawings forming a part of this specificationin which Figure 1,represents a front elevation of a complete string supp'ortingframe,embodying my invention.

Figure 2, represents an enlarged view of a portion of the individualstring supporting and regulating members.

Figure 3, represents a sectional side elevation of Figure 2, along lines33.

Figure 4, represents a diagrammatical arrangement of the stringregulating arrangement.

Figure 5, represents a front elevation of a complete string supportingframe of modified construction.

Figure 6, represents an enlarged view of the adjusting arrangement ofthe main string supporting bar.

Figure 7, represents a bottom view of Figure 6, along lines 77.

Similar characters refer to similar parts in all the views.

In Figure 1, a rigidly arranged frame structure comprising the verticalmembers 1 and 2, and the horizontal members 3 and 4, these memberspreferably made of light steel tubing and joined by suitable fittings 5,constitute the main sup frame- 1925. Serial No. 9,127.

Members 1 and 2, project beyond fittings 5, at the upper and lowerextreme ends so as to rovide proper supports, intended to fit intosuitable sockets 6, of the instrument body or casing.

Crossbars 7 and 8, suitably shaped to conform with the characteristic ofthe instr'uinent, are slidably arranged upon the vertical frame members1 and 2, this being accomplished by suitable sleeves 7 and 8, formingpart of the cross-bars 7 and 8. These cross-bars, as shown in Figures 6and 7 can be adjusted and set by specially arranged adjusting screws 9,provided with a right and left hand thread 10 and 11, engaging similarthreads cut in lug extensions fOlIIlsll'lg part of fittings 5, andsleeves 7 an The individual groups of tone strings 12, a

as shown in Figures 2 and 3, are mounted upon individual sliding blocks14. and held in position by string pins 15. Sliding blocks 14, are.movably arranged upon cross-bars 7 and 8, and conveniently held in placeby guide posts 16, slidinglv arranged in suitable slots 17 provided forthat purpose in cross bars '7 and 8. Adjusting screws 18, mount-- edupon cross-bars 7 and 8, engaging corresponding threads provided insliding blocks 14, serve the purpose of individual adjustment andregulating tone strings 12. The principles of adjustment are more readily understood by referring to the simplified and diagrammaticalillustration shown in Figure 4. In Figure 5, a modified construction ofa complete string frame is shown emphasizing the possible Variation inshape and form of such a frame, and also utilizing the individual stringadjust-ing feature on one end only, while the other ends of the tonestrings may be fastened in the commonly known and customary way.

Thus having described and illustrated an embodiment of my invention, Ido not wish to limit myself to any specific form of construction, itbeing apparent that there may be considerable variations in utilizingthe principles disclosed without departing from I the spirit of myinvention.

l/Vhat I claim to be new and desire to secure by Letters Patent is:

1. In musical instruments of the character described, the combination ofsuitable movable tone string supporting means, slidably arranged upon asuitable frame, and

' and individual tone string adjusting means movably arranged upon saidslidable tone string supporting means.

3. In a musical instrument of the character described the combination ofa s'lidably and adjustably arranged tone string supporting member, aplurality of suitable individual tone string mounting members,

said individual tone string mounting rnembers adn stably arranged uponsaid slldably supporting member," and individual tone string tension andregulating means for said individual tone string mountin members,

4. In musiea'linstrurnents of the shameter described the combination ofslidably and adjustab'ly arranged .tone string supporting members, aplurality of suitable individual tone string mounting members, saidindividual .tone string mounting members adjustably arranged upon saidslidably supporting members, and a'plura'lity of tone strin tension andregulating means forsai'd plurzility of individual tone string mount ingmembers. i

In musical instruments of the character described the combination of astationary frame, a slidably supporting bar adjustably arranged uponsaid stationary frame, a plurality ofindividual' tone string supports,said tone string supports movably and adjustablyarranged upon saidsl-idably supporting bar, and suitable regulating and parts of saidmusical instrument.

7. In a musical instrument of the string type, a rigid tubularsupporting structure,

suitable prongs extending from said tubular f'supporting structure, saidprongs so arranged as to engage in suitable pockets provided Within thebody of said musical instru ment, said pockets and said prongs soproportioned. as to easily engage and disengage without disturbing anyof the other-parts of sa-id musisal instrument. i 8. In musicalinstruments of the character describedfthe combination of a pl-urat ityof individual tone string carryingplates, said tone string oarr ingplates niovably mounted upon a suite le'common support, suitable guidepins forming part of said carrying plates engaging suitable slotsprovided in said common support, la plurality of suitable tone stringtightening pins adjustably mounted upon said tone string carryingplates,and suitable regulating screws engagin said tone string carrying platesand sai common support for the purpose of varying the tension of saidtone strings.
